Between May and October, temperature, dissolved oxygen, streamflow and transparency are monitored monthly by most WAV citizen monitors. Volunteer monitors also assess the aquatic and streamside habitat as well as the stream's macroinvertebrate community, using a biotic index. These two parameters are generally measured less often; habitat assessments are commonly completed once a year, in the spring, while the biotic index is generally assessed twice a year, once in the spring and again in the fall.
